The new Intel HD Graphics P4600 is considered to be an advancement of the previousgeneration Intel HD Graphics technologies that were first introduced in 2010. Each version including the new Intel HD graphics P4600 represents not a copy of the previous design, but an improvement, and today represents a new high-end offering of processor-based graphics for entry-level workstations. It offers an integrated ring bus technology that connects all CPU components (computational cores, L3 cache, graphics, and system agent with the memory controller) to enable an optimized approach of communicating with the system memory – via the fast L3 cache. The Intel HD Graphics P4600 processor-based graphics will support Microsoft DirectX11.1,* OpenGL* 4.0, OpenCL* 1.2 and DirectCompute 5.0 standards. In addition to improvements in both 2D and 3D graphics performance, Intel Quick Sync Video 2.0 technology almost doubles the H.264 transcoding speed of its predecessors and now supports up to 4K display resolutions. The graphics core microarchitecture improvements have produced noticeable improvement in 3D performance, of as much as 25%2 via 20 execution units and L3 cache. If your systems are to be employed by users of applications like the Autodesk AutoCAD*/Inventor*/Revit*; Adobe Premiere,* Adobe Photoshop,* After Effects,*SolidWorks* and other similar volume professional software applications, the Intel Xeon processor E3-1200 v3 product family with Intel HD Graphics P4600 offers competitive performance to entry-level professional discrete graphics cards. The Intel Xeon processor E3-1200 v3 product family with Intel HD Graphics P4600 represents a significant evolution for graphics and media capabilities. Updates to processor graphics include:
A scalable architecture partitioned into 5 domains consisting of:
– Global assets: Includes geometry front-end up to setup
– Slice common: Includes rasterizer, L3$ and pixel back-end
– Slice: shaders (EUs), IC$, samplers, Addrs Gen
– CODEX and media
– Displays
Significant 3D enhancements include Microsoft DirectX11, hardware tessellation, two programmable stages (HS and DS) and one fixedfunction Tessellator as well as new compressed texture format support for BC6H/7.
More key changes include:
– Increased number of Execution Units
– Enhanced compute shader support for data parallelism, UAVs, atomics, barriers
– Improved shared local memory for compute shaders
– Support for scatter gather
– Provision for shader model 5.1 (new DX11 instructions)
– Improved geometry performance
– Increase in Hi-Z performance
